| Abstract | ||||
| This study assessed the impact of oral administration of zinc oxide (ZnO) and selenium (Se) nanoparticles on milk production and gene expression in Baladi goats. Twenty-two pregnant females, 30 days before parturition, were divided into five groups: Group 1 (n=4) served as control; Groups 2 and 3 (n=4 each) received 150 mg ZnO and 0.3 mg of Se in microparticle (MP) forms, respectively; Groups 4 and 5 (n=5 each) received 15 mg ZnO and 0.03 mg Se in nanoparticle (NP) forms, respectively. Milk yield, composition, and gene expression related to milk production were analyzed. Results indicated a significant increase (P<0.001) in dry matter intake in the ZnO-NPs and Se-NPs groups, with an improved feed conversion ratio. Daily and overall milk yield, as well as fat-corrected milk yield, were highest in the NPs groups, particularly ZnO-NPs. Milk composition remained unchanged. Gene expression analysis showed significant upregulation of POU1F1, IGF-1, PPARγ, CSN2, and FASN in the NPs groups compared to the MPs and control groups, with the highest expression levels observed in the Se-NPs group. These findings suggest that ZnO-NPs and Se-NPs enhance milk production efficiency and upregulate key genes involved in milk yield in Baladi goats. | ||||
